At NEW FOCUS, we realize that photodetection, as the interface from your photonics experiment to your electronic instruments, is critical to extracting and preserving your experimental results. With over 15 years of experience, we strive to make photodetection simple (plug and play) while delivering the lowest noise and cleanest response possible.

NEW FOCUS is dedicated in bringing you Simply Better^TM Photonics.


	Balanced Receivers New Focus brings a wide variety of balanced receivers for your specific applications including: 1 MHz Large-Area Adjustable Balanced Receivers 10 MHz Adjustable Balanced Receivers 125-kHz Auto-Balanced Receivers 650- & 800-MHz Balanced Receivers 80-MHz Balanced Receivers For more comprehensive information regarding the balanced receivers available please Contact Us
	Beam Position Photoreceivers Position Sensitive Detectors These new Models 2930 position-sensitive detectors (PSDs) deliver exceptional performance with a range of convenient features. With <0.25-µm resolution, <±15-µm accuracy, and 16-bit digital output resolution, these detectors are ideal for beam position, pointing and power measurements. Available in 4x4 mm, 9x9 mm and 13x13 mm beam sizes.
	Beam Position Photoreceivers Quadrant- Cell Photoreceiver These quadrant-cell photoreceivers are ideal when you need to measure small deviations in the position of your laser beam, such as that required in beam-stabilization systems. Quadrant-cell photoreceivers consist of four individual yet identical photocells positioned very close to each other. Available in Si Quadrant Cell and InGaAs Quadrant Cell models.
	Detector and Receiver Acessories New Focus supplies detector and receiver accessories such as: 20-GHz Amplifiers Electrical Accessories (Accessory cables, Breakout cable, Adapter cable, Connector adapter) Filter Holders FC Fiber Adapter Power Supplies For more comprehensive information regarding the detector and receiver accessories available please Contact Us
	General Purpose Detectors and Receivers New Focus brings a wide variety of general purpose detectors and receivers for your specific applications including: 1 GHz Photoreceivers 10 MHz Adjustable Photoreceivers 125-MHz Photoreceivers 200 kHz Photoreceivers Nanosecond Photodetectors For more comprehensive information regarding the general purpose detectors and receivers available please Contact Us
	High Speed Detectors and Receivers New Focus brings a wide variety of high speed detectors and receivers for your specific applications including: <25-GHz Detectors and Receivers 12-GHz Amplified Free-Space Photoreceivers 12-GHz DC-Coupled Photoreceivers 12-GHz Photoreceivers 12-ps Photodetectors 18.5-ps Photodetectors 25-GHz Photodetectors 3.5-GHz DC-Coupled Photoreceivers 40- & 45-GHz Photodetectors For more comprehensive information regarding the high speed detectors and receivers available please Contact Us
	Large-Area & UV Quadrant Cell Photoreceivers These quadrant-cell photoreceivers are ideal when you need to measure small deviations in the position of your laser beam, such as that required in beam-stabilization systems. With their larger active areas, these versions can be used with larger beams, and/or measure larger deviations. Quadrant-cell photoreceivers consist of four individual yet identical photocells positioned very close to each other.
	Large-Area Photoreceivers With the extra-large diameter detectors in these photoreceivers, you'll be able to tweak your experiment without worrying about the beam wandering off the detector. Just position the detector close to where you think the laser beam is and you'll see a signal. No more time-consuming and tedious alignment procedures. Available in Si and Ge large area photoreceiver models.
	Power Meters New Focus brings a wide variety of power meters for your specific applications including: Handheld Power and Energy Analyzer High Dynamic Range^TM Power Meter Laser Power Analysis System Power Sensor Head and Accessories Ultracompact Laser Power Meter For more comprehensive information regarding the powermeters available please Contact Us
	10 Gbit/s VCSEL Designed for use in laboratory applications or for test and measurement of 10-Gbit/s datacom devices, the Model 1780 is an 850-nm, 10-Gbit/s, directly modulated, multimode vertical-cavity surface-emitting laser (VCSEL). The Model 1780 uses high-performance microwave circuitry to ensure clean delivery of the electrical input to the VCSEL chip, and the VCSEL's 50-µm output fiber enables the use of either 50-µm or 62.5-µm fiber.
	1-GHz Avalanche Photodiode (APD) Photoreceiver We are pleased to offer these APD photoreceivers for ultralow-light-level detection. These photoreceivers consist of a high-gain avalanche photodiode, followed by a low-noise amplifier and internal bias supply all in a compact module—no need for separate high-voltage input. We optimize the noise performance of these APDs while enhancing the overall sensitivity of the APD photoreceiver with the inclusion of a linear amplifier.
	Femtowatt Photoreceiver Our femtowatt photoreceivers are ideal when you need the ultimate in low-light-level detection. When used with a chopper and a lock-in amplifier, these receivers can easily achieve sensitivity levels in the femtowatt range. These receivers provide amazing amounts of gain and yet are easy to use, making the most difficult spectroscopy or fluorescence experiment a snap. Available in Si and InGaAs models.
